Enter GPS Coordinates into HDS 8

I picked up a few GPS coordinates from Bing Maps. When I went to create a new waypoint on HDS, it would not let me scroll up to the numbers indicated in the "W" direction. I was trying to install 35.96771170380278,-83.4774417877196.

The 3rd digit in the 35.96771170380278 will not enter because it won't let you scroll to a number that high (I think it stopped at 5).

Is this an incorrect GPS coordinate or is there something in HDS software I am missing???
